Multiple-function exercise with elliptical transmission device

ABSTRACT

An exerciser includes a rotatable disk rotatably connected on the frame of the exercisers and two first links are pivotably connected between an upright post on the frame and two second links which are pivotably connected to two third links. A sliding assembly has two guide members and each guide member has a groove, and two respective distal ends of the two third links are slidably engaged with the grooves. Two pedals are connected to the two third links and a board is connected to the two pedals by connection members  44.  The user stands on the board and operates the board to overcome the resistance from the rotatable disk.

FIELD OF THE INVENTION

The present invention relates to an exerciser with a ellipticaltransmission device which allows the user to simulate different types ofexercisers.

BACKGROUND OF THE INVENTION

A conventional elliptical exerciser is shown in FIG. 9 and generallyincludes a base 50, a transmission device 51, two handles 53, two links54 and two slide rods 56. The transmission device 51 is connected to thebase 50 and includes two disks 52, and the two handles 53 are connectedto a top of the base 50. The two links 54 are pivotably connected to tworespective lower ends of the handles 53 and the other ends of the towlinks 54 are pivotably connected to the slide rods 56 via the links 55.Two pedals 57 are connected to the slide rods 56 which are pivotablyconnected to the disks 52. Two distal ends of the slide rods 56 areslidably engaged with two grooves in two guide members 58. The userholds the two handles 53 and stands on the two pedals 57 so move theslide rods 56 along the grooves in the guide members 58. The slide rods56 are moved in an oval trace such that the user's feet are exercisedalternatively along two respective oval traces. However, theconventional elliptical exerciser can only provide elliptical exercisefor the two feet without any weight exercise and the mode for operatingthe elliptical exerciser cannot be changed.

The present invention intends to provide a multiple-function exerciserthat combine the two pedals as a large board so that the user cansimulate different types of exercisers such as windsurfing andsnowboarding.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 3, the exerciser of the present inventioncomprises a base 10 and a frame 11 is connected on the base 10. Theframe 11 includes a curved upright post 12 and two handles 13 areconnected to the curved upright post 12. A transmission device 20 isconnected to the frame 11 on the base 10 and has a rotatable disk 16which can be a magnetic-resistance wheel or any known disk that producesresistance. A link assembly 30 has two first links 31 which has tworespective first ends pivotably connected to the upright post 12 and tworespective second ends of the first links 31 pivotably connected to tworespective first ends of two second links 32.

A sliding assembly 40 has two guide members and each guide member has agroove 17. Two respective second ends 32 of the two second links 32 arepivotably connected to two middle portions of two third links 41. Tworespectively first ends of the third links 41 are pivotably connected tothe rotatable disk 16 and two respective second ends of the third links41 movably engaged with the grooves 17. Two pedals 42 are connected tothe two third links 41 and a board 43 is removably connected to the twopedals 42 by connection members 44. The user can stand on the board 43and tries to keep balance and pushes or pulls the board 43 to simulatedifferent types of exercises such as snowboarding or windsurfing.Because the two pedals 42 are actually moved alternatively up and downso that the user needs to twist his or her body to keep the balance andthis creates a lot of fun. The connection members 44 can be connected ontwo ends of the bottom of the board 43 as shown in FIGS. 3 and 4, or theconnection members 44 are located at a front end of the bottom of theboard 43 as shown in FIG. 5.

As shown in FIG. 2, the transmission device 20 has a resistance unit 21received therein which has a first wheel 211 which has a first shaft 15supported on two L-shaped trusses 14. A second wheel 212 has a secondshaft 23 supported on two plates on the frame 11 and a belt 22 isconnected to the first and second wheels 211, 212. An initial wheel 27is rotated about the second shaft 23 and a break device 28 is connectedto the initial wheel 27. A plate 24 has a middle portion pivotablyconnected to the second shaft 23 and a tension roller 25 is connected toan end of the plate 24. The other end of the plate 24 is connected toanother tension spring 26 which presses the tension roller 25 onto thebelt 22. The break device 28 includes a break shoe 281 which has one endpivotably connected to the frame 11 and the other end of the break shoe281 is connected with a tension spring 282 so that when pulling thespring by a cable by the user, the break shoe 281 is in contact with theinitial wheel 27 to break it.

FIGS. 6A and 6B show that the board 45 can be a T-shaped board and isconnected between the two pedals 42.

FIGS. 7A and 7B show another embodiment of the exerciser which comprisesa base 10 and a frame 11 connected on the base 10. The frame 11 includesa curved upright post 12 and two handles are connected to the curvedupright post 12. A transmission device 20 is connected to the frame 11on the base 10 and has a rotatable disk 16. A link assembly 30 has twofirst links 31 which has two respective first ends pivotably connectedto the upright post 12. A sliding assembly 40 has two second links 41and two respective second ends of the first links 31 are pivotablyconnected to two respective first ends of two second links 41. Tworespective second ends of the two second links 41 are pivotablyconnected to the rotatable disk 16 of the transmission device 20. Twopedals 42 are connected to the two second links 41 and a board 43 isconnected to the two pedals 42 by connection members 44. The two pedals42 and the board 43 are located between the upright rod 12 and thetransmission device 20.

FIGS. 8A and 8B show yet another embodiment of the exerciser wherein thetransmission device 20 and the link assembly 30 are received in a casingand the two pedals 42 on the two third links 43 extend out from thecasing. The board 43 is connected to the two pedals 42.
